Answer:
The monthly fee is $25, plus the installation fee
Step-by-step explanation:
685 - 85 = 600
1 yr = 12 months
so 24 months
600 / 24 = 25
An initial amount of 900 grows at a rate of 7% every month. Write an
exponential equation for the
amount y after x months,

Answer:
Radius.
Step-by-step explanation:
A line joining the center of a circle to a point on the circle is called a radius.
This ultimately implies that, it is the straight line from the center of a circle to any point on the edge of the circle. Also, radius is half of a diameter i.e diameter divided by the 2.
Generally, the radius is used for calculating the area and circumference of a circle.
Area of a circle = πr²
Circumference of a circle = 2πr
The S.I units for measuring radius is meters.
Please solve this for me.
Answer:
x = 14
Step-by-step explanation:
Figure A to Figure B = 1:3.5 = 1/3.5
Therefore:
Side length of figure A to side length of figure B = 1/3.5
Thus:
4/x = 1/3.5
Cross multiply
x*1 = 3.5*4
x = 14
What is the value of x in the equation 2x - 3/5 = -1/10
Answer:
1/4
Step-by-step explanation:
you add 3/5 to the other side and find the lcm making it 6/10--1/10=5/10. Then 5/10 divided by 2 = 2.5/10 which you can simplify to 1/4.
Answer: x=1/4
Step-by-step explanation:
1. Isolate x: if you move -3/5 to the other side, your equation would become
=> 2x=-1/10+3/5
2. Find the common denominator: since you can't add -1/10 with 3/5 without simplifying, you're equation would change to this:
=> 2x=-1/10+6/10
3. Simplify:
=> 2x=5/10 => 2x=1/2
4. Divide:
=> 2x=1/2 => x=1/2*1/2 => x=1/4

A conference consists of 5 sessions: A, B, C, D, and E. Here are the costs of the sessions.
Session A: $50
Session B: $50
Session C: $100
Session D: $150
Session E: $200
A participant plans to attend 3 sessions. Here is a list of all possible samples of size 3 sessions from this population of 5 sessions: ABC, ABD, ABE, ACD, ACE, ADE, BCD, BCE, BDE, and CDE. If sessions A, B, and C are selected, what is the sample minimum session cost?
$50
$66.67
$100
$200
When the list of all possible samples of size 3 sessions from this population of 5 sessions are given. The sample minimum session cost should be considered as the $200.
Calculation of the sample minimum session cost:Since
Session A: $50
Session B: $50
Session C: $100
Session D: $150
Session E: $200
So here the minimum cost be
= $50 + $50 + $100
= $200
hence, The sample minimum session cost should be considered as the $200.

F(x)=2x+1 then find f(k)
Answer:
f(k) = 2*k + 1
Step-by-step explanation:
The 'f' function takes the variable, doubles it, and then adds 1.
So f(k) = 2*k + 1
f(g) = 2*g + 1
f(m) = 2*m + 1, and so on
It doesn't really matter which variable you use, the function still does the same thing to it.

Which statement about the properties of Function A and Function B are true?
Select each correct statement.
A The Y-intercept of Function A is equal to the Y-intercept of Function B.
B The Y-intercept of Function A is less than the Y-intercept of Function B.
The Y-intercept of Function A is greater than the Y-intercept of Function B.
D The rate of change of Function A is equal to the rate of change of Function B.
E The rate of change of Function A is less than the rate of change of Function B.
Answer:
B. The Y-intercept of Function A is less than the Y-intercept of Function B
F. The rate of change of Function A is greater than the rate of change of Function B
Step-by-step explanation:
Function A rate of change and y-intercept:
✔️Rate of change using two pairs of values from the given table, (1, 2) and (3, 10):
Rate of change = ∆y/∆x = (10 - 2) / (3 - 1) = 8/2 = 4
Rate of change (m) of Function A = 4
✔️ To find the y-intercept (b) of function A, substitute (x, y) = (1, 2) and m = 4 into y = mx + b (slope-intercept form):
2 = 4(1) + b
2 = 4 + b
2 - 4 = b
-2 = b
b = -2
Y-intercept (b) of function A = -2
Function B rate of change (m) and y-intercept (b):
The function, y = 3x + 4 is given in the slope-intercept form, y = mx + b.
Therefore,
Rate of change/slope (m) = 3
Y-intercept (b) = 4
The following staments about the properties of both functions are therefore true:
B. The Y-intercept of Function A is less than the Y-intercept of Function B
F. The rate of change of Function A is greater than the rate of change of Function B

Answer:
One of the angles in the triangle might be 50.
AND
The length of the third side must be 11cm or smaller.
Step-by-step explanation:
-The triangle might be an equilateral triangle (having all the same sides and angles). False, since the triangle sum theorem states that all angles inside of a triangle must add up to 180, so an equilateral triangle would need to have all three angles at 60 degrees.
-One of the angles in the triangle must be 120 (false; it can be anything above 90, which is not only 120)
-The length of the third side must be 11cm or smaller. (True, Triangle Inequality Theorem)
-One of the angles in the triangle might be 50 (possibly, so very much true)

$70Step-by-step explanation:
ExplanationIf we reverse it we can break it down easier: We start at $935
15 dollars on every purchase, he sold 11 TVs. So we find the total amount of money, 15*11=165
935-165=770
770 is the amount left without the money he has earned so the total base.
770/11=70
Checking answerLet's rebuild it to test if it is correct...
$70 for each tv * 11 tv's = $770 or the base price of the tv's
$15 for all the warranties
$15*11=165
165+770=935
So the answer is 70$
Hopefully, this helped.

3) A grocery store has cereal on sale. If the original price is $4.50 and the sale
price is $3, what percent is the discount?
Step-by-step explanation:
original price = $4.50
sale price = $3
discount price = $4.50 - $3
= $1.50
discount = discount percent × original price ÷ 100
$1.50 = discount percent × $4.50 ÷ 100
discount percent = $1.50 × 100 ÷ $4.50
= 33.33%

Answer:
110º
Step-by-step explanation:
Because the angle starts at 10º, and ends at 120º, so if we moved the angle down to start at 0º we would have to subtract 10º, so we must subtract 10º from 120º. You end up with 110º.

Use the Law of Sines to determine the length of
side c.
44°
B
29
49
34
21
Answer:
c = 29
Step-by-step explanation:
Law of sines is given as: [tex] \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
B = 180 - (57 + 44) = 79°
b = 41
C = 44°
c = ?
Thus:
[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
Substitute
[tex] \frac{41}{sin(79)} = \frac{c}{sin(44)} [/tex]
Multiply both sides by sin 44
[tex] \frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44) [/tex]
[tex] \frac{41*sin(44)}{sin(79)}*sin(44) = c [/tex]
c = 29.0140633 ≈ 29
